Question for any practitioners or students from Scotland.

I was at a talk a few months or so back where a speaker from Tayside dental school was discussing a caries management approach called the Hall technique. I've been reading a little bit about this and the theory sounds awesome but I'd never heard it before, let alone been given a lecture on it, and as far as I know English schools don't teach it. Any Scottish practitioners got hands on experience of this and can attest to the results?
